摘　　要：近年来 ,空气离子特别是空气负离子的保健作用受到人们的普遍关注。空气离子浓度也是衡量空气清洁度的重要指标之一。森林地区空气负离子浓度明显高于其它地区 ,成为重要的森林旅游资源。文中就空气负离子的来源、时空变化、森林与空气负离子的关系、空气负离子的保健及治疗功能 。In recent years,the health function of air ions,especially of air anion has received an universal attention.The density of air anion has become one of the important indexes that measure the sanitation degree of the air.The air anion in the forest areas,obviously with a higher density than that in other areas,is an important forest tourism resource.This paper makes a summary of the origin of air anion and its temporal and spatial variation,the relationship between forest and air anion,the health and treating function of air anion as well as the assessment standard of the air sanitation degree which uses the density of the air anion as the index.
